At one of our customers in Switzerland we have a V-Series V6080 MetroCluster with Hitachi VSP Backend Storage and two FAS6040 as Nearstore System with DS4243 containing 2TB S-ATA Disk Drives.
The V-Series V6080 serving nfs, iSCSI and CIFS, are running DOT 7.3.4
The Nearstores FAS6040 running 8.0.1 with 64bit aggregates as snapvault destination
As a company policy the dns servers configured on the server systems and storage controllers do not allow resollving hostnames or URL outside of the company network.
We set the autosupport options in order to post ASUP messages to NetApp using https and configured the proxy server with the correct tcp port number.
-> This cannot be configured with Systems Manager! Systems Manager allow only plain ip addresses, no sockets like 192.168.222.34:3233 😞
toaster> options autosupport.support.transport https
this works perfectly well on the Systems running 7.3.4
But it does not work with 8.0.1. The OnTap complains, the ASUP URL support.netapp.com cannot be resolved!!
To me it seems as:
DOT 7.3.4 sends the ASUP message to the Proxy with the recipients URL; the proxy then resolves the URL and forwards the message properly
DOT 8.0.1 first resolves the URL to an IP Address and sends the message with the IP-Address as a recipient to the proxy server and the proxy forwards it to NetApp.
We workaround the different behaviour by adding a line in the /etc/hosts to resolve the ASUP URL. But this is not what we like.
I opened a case for this but the issue was not understand by NetApp Support.
Any help is apprechiated!!
